“…The best match with theoretical band gap of kesterite was obtained with reaction time 30 hr samples prepared by solvent-thermal reflux process. Corresponds well with the 1.4-1.56 eV reported in the literature, which is near the optimum value for photovoltaic material in great potential [56]. In summary, the optical bandgap of time based properties are the indication of existing and transformation of different phases during transformation into CZTSe at 30 hr with bandgap of 1.42eV which is suitable for the application in solar cell.…”

This paper reports on the reaction mechanism of Cu 2 ZnSnSe 4 (CZTSe) nanoink via a solvent-thermal reflux method using copper (Cu), zinc (Zn), tin (Sn), and selenium (Se) powders as precursors and polyetheramine as a reaction solvent. The formation of CZTSe nanoparticles in polyetheramine began with the formation of binary phase CuSe 2 due to the strong catalysis provided by polyetheramine. This was followed by the formation of binary phase ZnSe crystals. In the final stage, ternary crystals of Cu 2 SnSe 3 transformed into well-dispersed nanocrystals of Cu 2 ZnSnSe 4 , which are derived from characterization of XRD, Raman and TEM. The size of the crystals was shown to decrease with reaction time due to the emulsification effect of the polyetheramine epoxy group. Quaternary phase CZTSe firstly appeared at 20 hr, and then the composition of the CZTSe tended to become Cu-poor and Zn-rich over time. The proposed reaction mechanism of CZTSe nanoparticles in polyetheramine presented a distinct phase transformation and suitable time-composition properties, which benefited to further solution-based solar cell application.

“…Hot-injection solution synthesis method is one of the most commonly used methods to prepare CFTS nanocrystals. However, this method needs complex devices in which the precursors are rapidly injected into a hot organic reaction medium, and the reaction is extremely vigorous which may be very dangerous at high temperature condition [14,15]. CFTS nanocrystals with features of high purity, uniform particle size and regular morphology have also been synthesized through solvothermal synthesis method.…”

“…In addition, selenization is totally avoided, thus it is environmental positive. Other routes based on nanoparticles 23 , solvothermal [24][25][26] , rotatory ball milling 27 , microwave 28 , hot-injection 25,[29][30][31][32] or non-injection methods 33 , spray pyrolisis 34 have been also applied, but with inferior effectiveness for CZTSSe production.…”

Abstract:An easy method to obtain kesterite Cu2ZnSn(Se1-x,Sx)4 (CZTSSe) solid solution as an absorber for thin film photovoltaic solar cells is discussed in this report. Particular emphasis is directed toward the procedure´s steps of the CZTSSe preparation, as well as its structure and properties. For the preparation of CZTSSe an easy, low-cost and sustainable aqueous precipitation method that included chemical transformations of metal selenite precipitate, its reduction to metal selenides and further crystallization of kesterite, is applied. This procedure is more viable as avoids the use of selenization treatment and thus generation of toxic vapors and employs water as a solvent instead of organic compounds. In addition, the proposed procedure is very attractive way of preparation for industrial large-scale fabrication of the most promising absorber candidates for photovoltaic thin film solar cells.Kesterite CZTSSe solid solution has been prepared and characterized in terms of chemical composition, structural and morphological transformations, as well as optical and electrical properties, confirming the viability and effectiveness of the applied process.The optimal electrical parameters obtained of the device are 21.5 mA/cm2, 532 mV, 42.8%., and 4.9% to short circuit current (Jsc), open circuit voltage (Voc), fill factor (FF), and efficiency (Eff.) respectively. Detailed description of each procedure steps and full characterization of the products, starting from as-prepared, intermediate and final compound is also exposed that could be very useful for any experimental scientist.2
